On the bunker-ig site it is mentioned, that the whole report was taken from
Waffen-Revue 48 / Waffen-Lexikon 2628-100-2. And, although I cannot say
anything about the reliability of this source/report, the parts where actual
results are mentioned sound plausible : No real results !
One mentioned method was aimed at producing updraughts by spreading and
igniting fuel from lower flying aircraft. Those updraughts should be strong
enough to destroy a bomber. So, that's not a method to stop an engine.
Later it is said, that materials were developed, which released substances by
smouldering, that could stop an reciprocating engine in a few minutes. But this
method worked only for engines up to 2.5l cylinder capacity and surely those
joss sticks would have to be brought in very close vicinty of the engine ?
Ozonewas tried as an "engine stop substance", too, but again the problem was,
how to achieve a sufficient concentration arounf the engine ?
And then a method to stop the ignition system of an engine was proposed by a
german company, using ionisation, but even the report says, that nobody in this
ingenius company had the slightest idea, how to ionize at will the air around a bomber
or a tank in some distance.
But all those "projects" may have been worthwhile, as they kept technical personal
busy up to the last day of the war in europe, saving them from being send to the front !
